A more safe way to run shell command is using "check_output" function. If the return value if not 0, a exception raised, otherwise return the command output. $ cat myrun.py import subprocess def run(cmd):returnsubprocess.check_output(cmd, shell=True) $ python -i myrun.py >>> ret ...

使用Python编写Run命令可以通过subprocess模块来实现。subprocess模块提供了创建子进程并与其进行交互的功能。 下面是一个示例代码,展示了如何使用Python编写Run命令: 代码语言:txt 复制 import subprocess def run_command(command): process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subproc...

当从外部输入生成命令参数时,需特别注意避免命令注入(command injection)漏洞。建议使用列表形式的参数传递,以确保参数被正确地处理而不是直接作为命令执行。 ```python # 不推荐:可能导致命令注入 command = f"ls {user_input}" subprocess.run(command, shell=True) ...
python之执行shell命令 python 执行shell命令,且执行完后将shell端的输出返回 subprocess 模块首先推荐使用的是它的 run 方法,更高级的用法可以直接使用 Popen 接口。 run 方法语法格式如下: subprocess.run(args, *, stdin=None, input=None, stdout=None, stderr=None, capture_output=False, shell=False, cwd...
